Any plan to support retina resolution?

It looks kind of blurry on my macbook pro retina, maybe I've missed something.

I think it looks fine unless you are using pictures as background or elements.

Actually, it's not very sharp, there is some tricks we can do to make a canvas retina-compatible: http://web.archive.org/web/20130415082122/http://joubert.posterous.com/crisp-html-5-canvas-text-on-mobile-phones-and

I don't have a lot experience with that though.

Simply resizing the canvas to width / devicePixelRatio is problematic for the mouse events in arborjs, though. You'll have to adjust your calculations for touch events to incorporate the particleSystem.screenSize setting; otherwise, your mouse events won't work as you expect them to. (For example, dragging on the screen affected a node in a different part of the screen when I tried to adjust for a Retina display; I'm still working on the solution to this.)
